Cyclopentane is also used in the manufacture of synthetic resins and rubber adhesives. [citation needed] Cyclopentane is a minor component of automobile fuel, with its share in US gasoline varying between 0.2 and 1.6% in early 1990s [8] and 0.1 to 1.7% in 2011. [9] Its research and motor octane numbers are reported as 101 or 103 and 85 or 86 ...
It is a saturated cyclopentane with three methyl substituents branching off carbons 1,2, and 3. The methyl groups off carbons 1 and 3 are trans with respect to each other, while the methyl group off carbon 2 has undefined stereochemistry , allowing it to be either cis or trans with respect to methyl 1 or 3.
A heterocyclic compound or ring structure is a cyclic compound that has atoms of at least two different elements as members of its ring(s). [1] Heterocyclic organic chemistry is the branch of organic chemistry dealing with the synthesis, properties, and applications of organic heterocycles .
1,2,3,4,5-Cyclopentanepentol, also named cyclopentane-1,2,3,4,5-pentol or 1,2,3,4,5-pentahydroxycyclopentane is a chemical compound with formula C 5 H 10 O 5 or (–CHOH–) 5, whose molecule consists of a ring of five carbon atoms (a cyclopentane skeleton), each connected to one hydrogen and one hydroxyl group.

Gonane is a tetracyclic hydrocarbon with no double bonds. It is formally the parent compound of the steroids, hence it is called the "steroid nucleus". [1] [4] [5] Some important gonane derivatives are the steroid hormones, characterized by methyl groups at the C10 and C13 positions and a side chain at the C17 position.
A drug class is a group of medications and other compounds that share similar chemical structures, act through the same mechanism of action (i.e., binding to the same biological target), have similar modes of action, and/or are used to treat similar diseases. [1] [2] The FDA has long worked to classify and license new medications.
The chemical structure is exemplified by iridomyrmecin, a defensive chemical produced by the ant genus Iridomyrmex, for which iridoids are named. Structurally, they are bicyclic cis-fused cyclopentane-pyrans. Cleavage of a bond in the cyclopentane ring gives rise to a subclass known as secoiridoids, such as oleuropein and amarogentin.
